Hmm, it should be using the compiler that was used to compile your
Python. Check if you've got a environment variable CC defined (echo
$CC at the command line). If you do, remove it. If you don't, set it
to gcc, and try again.

If you've got trouble compiling Numeric, you'll probably have trouble
compiling all other extensions. Have a look in the Makefile that was
installed with Python (from the paths in your output above, I figure
it's at
/home/rathlefs/languages/activePython/lib/python2.4/config/Makefile)
and check to see what the CC variable is defined as. If it's not gcc,
then I would assume that your Python was built with cc.

Is Active Python for Solaris a binary distribution (as in, it doesn't
compile it from source)? If that's so, it was probably done with the
Sun compiler, and would expect to use that for compiling extensions.
If that's the case, I'd look into compiling Python from source (it's
really not that hard), which will use your GCC compiler. I have *no
idea* on the compatibility of the Sun and GCC compilers (but I can
tell you that if you've got C++ code, they aren't). I know I've run
into fun on Alpha machines, trying to mix the Compaq compiler and GCC.
